When the stroller 100 is to be used, the rider 50 is pulled in the direction of the unfolding trend of the stroller 100 , and under the effect of the gravity of the stroller 100 itself, the blocking portion 12 is released from the seat tube 60 , thereby unfolding the stroller 100 .

FIG4 shows a schematic side view of a stroller provided with a folding lock according to an embodiment of the present application. As shown in FIG3 and FIG4 , in order to make the first end of the blocking portion 12 easily cooperate with the blocking seat 13 and make the stroller 100 easier to fold, in some schematic examples of the present application, the blocking seat 13 is provided with a recess 132, and the outer edge of the recess 132 is provided with a guiding slope 131. The position of the recess 132 corresponds to the position of the first through hole 301 when the stroller 100 is in the folded state.

FIG5 shows a folding process diagram of a baby stroller provided with a folding lock according to an embodiment of the present application. As shown in FIG5 , during the folding process of the baby stroller, the blocking seat 13 moves upward as the center of gravity of the baby stroller 100 rises. When the baby stroller 100 approaches the folded state, the position of the blocking seat 13 is close to the position of the blocking portion 12. As the folding process progresses, under the action of an external thrust, the first end of the blocking portion 12 moves on the surface of the blocking seat 13 along the guide slope 131 provided on the surface of the blocking seat 13. When the baby stroller 100 is folded into place, the first end of the blocking portion 12 is inserted into the concave portion 132 of the blocking seat 13, thereby locking the relative position of the vegetable basket tube 40 in the baby stroller 100, and realizing automatic locking of the folded baby stroller. The provision of the guide slope 131 enables the first end of the blocking portion 12 to be gradually inserted into the concave portion 132 of the blocking seat 13, thereby preventing the blocking portion 12 from being impacted by the blocking force of the blocking seat 13, thereby more easily realizing stable and automatic locking of the folded baby stroller.

FIG6 is a schematic cross-sectional view of a stroller provided with a folding lock according to an embodiment of the present application, and FIG7 is a partially enlarged schematic view of A in FIG6. As shown in FIG6 and FIG7, in order to reduce the resistance of the guiding slope 131 to the first end of the blocking portion 12, so that the first end of the blocking portion 12 can be more easily inserted into the recess 132 along the guiding slope 131 provided on the surface of the blocking seat 13, the first end of the blocking portion 12 is provided as a rounded transition surface 121. In some exemplary examples, the first end of the blocking portion 12 is provided as a chamfered transition surface.

In some exemplary examples, as shown in FIG6 and FIG7 , the inner side wall 134 of the recess 132 is an inclined surface inclined toward the periphery. In this way, when the stroller 100 is folded, the first end of the blocking portion 12 can be gradually inserted into the recess 132 along the inclined inner side wall 134 of the recess 132, thereby smoothly locking the blocking seat 13. When the stroller 100 is unfolded, the first end of the blocking portion 12 can be gradually separated from the recess 132 along the inclined inner side wall 134 of the recess 132, thereby reducing the resistance of the blocking seat 13 to the blocking portion 12, making it easier to unfold the stroller 100.

In order to make the folding lock lock the folded baby stroller 100 more firmly, and to easily unlock the folding lock and unfold the baby stroller when the baby stroller needs to be used, in some schematic examples, as shown in Figures 6 and 7, the folding lock of the present application further includes an elastic element 14. The elastic element 14 is disposed in the first opening 111 of the fixing portion 11, the first end of the elastic element 14 abuts against the bottom surface of the first opening 111, and the second end of the elastic element 14 abuts against the second end of the blocking portion 12. When the baby stroller 100 is close to the folded state, the position of the blocking seat 13 is close to the position of the blocking portion 12, and the elastic element 14 is in a natural state. As the baby stroller 100 is folded, the first end of the blocking portion 12 moves along the guide slope 131 on the surface of the blocking seat 13 under the action of external thrust, and the elastic element 14 is in a gradually compressed state during this process. When the baby stroller 100 is folded into place, the blocking portion 12 is pushed toward the blocking seat 13 under the action of the elastic force of the elastic element 14, and the first end of the blocking portion 12 is inserted into the recess 132 of the blocking seat 13 and abuts against the bottom surface of the recess 132, thereby locking the relative position of the vegetable basket tube 40 in the baby stroller 100, and realizing automatic locking of the folded baby stroller. FIG8 shows a schematic side view of a folded baby stroller 100 provided with a folding lock according to an embodiment of the present application. As shown in FIG8 , after the baby stroller 100 is folded, the blocking portion 12 is inserted into the blocking seat 13, and the blocking portion 12 and the blocking seat 13 are locked with each other, thereby locking the relative position of the vegetable basket tube 40 in the baby stroller 100 to prevent the baby stroller 100 from automatically unfolding after being folded. In this way, the folding lock achieves locking of the folded baby stroller 100. When the baby stroller 100 needs to be unfolded, the blocking portion 12 compresses the elastic element 14 under the thrust of the side wall of the recess 132, and the blocking portion 12 is separated from the blocking seat 13, thereby unlocking the vegetable basket tube 40 and further unfolding the baby stroller 100.

In some exemplary embodiments, as shown in FIG6 and FIG7 , the second end surface of the blocking portion 12 is provided with a receiving opening 122, and the second end of the elastic element 14 abuts against the receiving opening 122 of the blocking portion 12. In this way, when the stroller 100 is folded or unfolded, the elastic element 14 can abut against the blocking portion 12 more stably.

In some exemplary examples, as shown in FIG6 and FIG7 , the first end and the second end of the blocking portion 12 are both cylindrical structures, and the outer diameter of the second end of the blocking portion 12 is larger than the outer diameter of the first end of the blocking portion 12; the first opening 111 of the fixing portion 11 and the first through hole 301 on the rear leg frame 30 are both round holes; and the outer diameter of the first opening 111 is larger than the outer diameter of the first through hole 301. In this way, when the baby stroller 100 is folded or unfolded, the first end of the blocking portion 12 passes through the first through hole 301 on the rear leg frame 30, and the second end of the blocking portion 12 is restricted in the first opening 111 of the fixing portion 11, so that the blocking portion 12 can be prevented from easily falling off the rear leg frame 30.

In one embodiment of the present application, the frame member is a handlebar 50 of the baby stroller 100. The fixing portion 11 of the folding lock is fixedly connected to the handlebar 50 of the baby stroller 100; and the blocking portion 12 of the folding lock is connected to the fixing portion 11. The folding lock further includes a blocking seat 13, which is connected to the basket tube 40 or the seat tube 60 of the stroller 100 and is located at a position corresponding to the blocking portion 12 when the stroller 100 is in the folded state; the blocking portion 12 is configured to cooperate with the blocking seat 13, and lock the basket tube 40 or the seat tube 60 after the stroller 100 is folded, thereby realizing automatic locking of the folded stroller 100. When the stroller 100 is to be used, the rider 50 is pulled in the direction of the unfolding trend of the stroller 100 , and under the gravity of the stroller 100 itself, the blocking portion 12 unlocks the basket tube 40 or the seat tube 60 , thereby unfolding the stroller 100 .

FIG9 shows a three-dimensional structural schematic diagram of a folded baby stroller provided with a folding lock of the second embodiment of the present application. As shown in FIG9 , in another embodiment of the present application, the folding lock comprises a fixing portion 21 and a blocking portion 22. The frame member is a front leg frame 20.

The blocking portion 22 is connected to the fixing portion 21, and the blocking portion 22 is configured to lock the basket tube 40 or the seat tube 60 on the baby stroller 100 when the baby stroller 100 is in the folded state.

Figure 10 shows a schematic side view of a folded baby stroller provided with a second embodiment of a foldable lock of the present application, and Figure 11 shows a schematic side view of an unfolded baby stroller provided with a second embodiment of a foldable lock of the present application. As shown in Figures 9-11, in some schematic examples of the present application, the fixing portion 21 is provided at the lower end of the front leg frame 20, one end of the fixing portion 21 is fixedly connected to the front leg frame 20, and the blocking portion 22 is fixedly connected to the other end of the fixing portion 21. When the stroller 100 is folded, the folding lock locks the relative position of the basket tube 40 in the stroller 100, blocking the unfolding trend of the stroller 100, thereby preventing the folded stroller 100 from unfolding automatically. When the stroller 100 needs to be used, the handle 50 is pulled in the unfolding direction of the stroller 100, and under the gravity of the stroller 100 itself, the basket tube 40 or the seat tube 60 is unlocked from the blocking portion 22, thereby unfolding the stroller 100. The folding lock of the embodiment of the present application can realize the quick and convenient automatic locking of the folded baby stroller, and can conveniently unfold the locked baby stroller 100 when needed.

In order to lock the folded baby stroller 100 more conveniently and quickly, as shown in FIGS. 9-11 , in some exemplary examples of the present application, the blocking portion 22 is a magnet. The magnet is configured to be adsorbed on the basket tube 40 when the baby stroller 100 is in the folded state, thereby easily locking the basket tube 40 and preventing the folded baby stroller from unfolding by itself. When the baby stroller 100 needs to be used, the basket tube 40 is gently pushed in the unfolding trend direction of the baby stroller 100 to separate the basket tube 40 from the magnet, thereby unlocking the basket tube 40 and conveniently and quickly unfolding the baby stroller 100. In some embodiments, the magnet can also adsorb the seat tube 60 or the rear leg frame 30, but is not limited thereto. In one embodiment, as shown in FIG. 9 , a connecting piece 211 is disposed at the other end of the fixing portion 21, and the magnet is embedded in a slot 2111 opened on the connecting piece 211 toward the corresponding vegetable basket tube 40 or the seat tube 60.

FIG12 shows a three-dimensional schematic diagram of a folded baby stroller 100 provided with a folding lock according to a third embodiment of the present application. As shown in FIG12 , in the third embodiment of the present application, the folding lock comprises a fixing portion 31 and a blocking portion 32. The fixing portion 31 is fixedly connected to the front leg frame 20 of the baby stroller 100. The blocking portion 32 is connected to the fixing portion 31, and the blocking portion 32 is configured to lock the basket tube 40 or the seat tube 60 of the baby stroller 100 when the baby stroller 100 is in the folded state.

Specifically, the fixing portion 31 is disposed at the lower end of the front leg frame 20, and one end of the fixing portion 31 is fixedly connected to the front leg frame 20. The blocking portion 32 is fixedly connected to the other end of the fixing portion 31.

FIG. 13 shows a schematic cross-sectional view of a stroller provided with a third embodiment of a folding lock according to the present application, as shown in FIG. 12 and FIG. 13 , in some exemplary embodiments, the blocking portion 32 is an elastic portion; when the stroller 100 is in the folded state, the blocking portion 32 is partially sandwiched between the rear leg frame 30 and the vegetable basket tube 40, and partially passes through the rear leg frame 30 and the vegetable basket tube 40 of the stroller. In some embodiments, when the stroller 100 is in the folded state, the blocking portion 32 is partially sandwiched between the rear leg frame 30 and the seat tube 60 of the stroller 100, and partially passes through the rear leg frame 30 and the seat tube 60 of the stroller 100. According to this embodiment of the present application, as the baby stroller is folded, the basket tube 40 or the seat tube 60 approaches the rear leg frame 30, and squeezes and passes over the blocking portion 32. After being folded into place, the blocking portion 32 is clamped between the rear leg frame 30 and the basket tube 40, or between the rear leg frame 30 and the seat tube 60, thereby limiting the relative position of the basket tube 40 or the seat tube 60 in the baby stroller 100, and realizing automatic locking of the folded baby stroller. When the baby stroller 100 needs to be unfolded, the basket tube 40 or the seat tube 60 unfolds in the unfolding direction under the weight of the baby stroller 100 itself or the external thrust, and squeezes and passes over the blocking portion 32, and the blocking portion 32 unlocks the basket tube 40 or the seat tube 60, thereby further unfolding the baby stroller 100. In addition, the blocking portion 32 is configured as an elastic portion, so that the automatic locking of the folded baby stroller 100 is firm and reliable, and at the same time, only a small thrust is required to easily achieve the automatic locking or unfolding of the folded baby stroller 100.

In some exemplary embodiments, as shown in FIG13 , the elastic direction of the elastic portion is set to be the lateral direction of the stroller 100 when the stroller 100 is in the folded state. In this way, the basket tube 40 or the seat tube 60 can be better locked in a position aligned with the rear leg frame 30, which increases the difficulty of the basket tube 40 or the seat tube 60 to unfold automatically after the stroller 100 is folded, and increases the stability of the locking.

In some exemplary embodiments, as shown in Fig. 13, the elastic portion is a hollow elastic portion. This arrangement can greatly reduce the external thrust required for the basket tube 40 or the seat tube 60 to squeeze and pass over the elastic portion, making it easier to automatically lock the folded stroller and unfold the stroller when the stroller needs to be used.

Another aspect of the present application provides a baby stroller. As shown in FIG. 1 , the baby stroller 100 includes a front leg frame 20, a rear leg frame 30, a vegetable basket tube 40, a rider 50, and a seat tube 60. The baby stroller further includes any one of the folding locking members described in the above embodiments disposed on the baby stroller 100.

The baby stroller of the present application can realize automatic locking of the folded baby stroller through the folding locking member provided on the baby stroller 100, and can conveniently unfold the locked baby stroller when the baby stroller needs to be used.

The above disclosure is only the preferred example of this application and cannot be used to limit the scope of this application. Therefore, equivalent changes made according to the claims of this application are all within the scope covered by this application.
